Patent CA-2306058-A1 (CA)
Inventor: ROCKENBACH MANFRED
IPC: E05F15/608
Filed: 1999-08-12
Abstract: The present invention relates to a revolving door that comprisesa ceiling driving support (10) which is integrated in a ceiling structure (7) comprising two segments (8, 9). This invention is characterised in that the ceiling driving support (10) is arrangedbetween the segments (8, 9), extends on the inner diameter of thetop edge band (11) and is connected to said top edge band (11) on the front side. It is thus possible to provide a member that rigidifies and reinforces the ceiling structure (7) so that other members in the ceiling structure, e.g. the mounts supporting the top edge band (11), can be designed at lower cost and with a reduced weight. When adapting the ceiling driving support (10) to topedge bands (11) having different diameters, only the ceiling driving support (10) needs to be elongated on the front side as its cross-section remains the same.

Inventor: KETCHAM MARK G
IPC: F16L37/098
Filed: 2000-05-29
Abstract: A coupling assembly comprising a female connector body, a male member, a retainer and a dust barrier. The female connector body defines a bore extending axially inward into the connector body from an entrance. A radial face is defined in the bore axially inward of the entrance. The male member is received within said bore. The male member is formed at the end of a tube and includes a projection extending radially from the tube. The retainer has at least two locking beams extending between the radially extending projection and the radial face to retain the male member in the bore. The locking beams defines a slot between the locking beams. The dust barrier is slidably mounted on the tube. The dust barrier has at least one extension insertable within the slot so as to prevent inadvertent radially inward movement of the locking beams. Wherein upon sliding the dust barrier toward the female connector body, the dust barrier encloses the bore so as to prevent foreign material from entering the coupling assembly.

Title: Radio location system including transceiver tags
Inventor: BOYD ROBERT W
IPC: G01S5/02
Filed: 1999-01-28
Abstract: An asset management radio location system uses time-of-arrival differentiation for random and repetitive spread spectrum, short d oration pulse "blinks" from object attached tags, to provide a practical, continuous identification of the location of each and every object within an environment of interest, irrespective whether the object is stationary or moving. Correlation-based RF processors (24) determine which signals received by tag transmission readers (10) are first-to-arrive signals as transmitted from any blinking tag, and an object location processor carries out time-of-arrival differentiation of these first to-arrive transmissions from any blinking tag to determine where the respective object is located within the environment. A low power interrogation wand may be employed to refine the location of an object by a user programmed transmission - response exchange between the wand and the tag associated with the object of interest.
